Sony's widest full-frame E-mount zoom can give you fresh, dynamic ways of seeing a wide range of subjects. Its ultra-wide 12-24mm optics feature cutting-edge refinements for stunning corner-to-corner G Lens resolution at all apertures, while quiet, fast, precise autofocus make it ideal for movies as well as stills. It is an excellent choice for landscapes and architecture, and is compact, lightweight, and mobile so it can go wherever the great shots are without slowing you down.

Advanced optics capture stunning ultra-wide imageryAchieving ideal performance at wide angles can be difficult, but innovative Sony optical technology has the answers. Aspherical elements contribute to outstanding resolution from the center of the image right out to the periphery, while ED (Extra-low Dispersion) and Super ED glass elements effectively suppress chromatic aberration. Sony's acclaimed Nano AR Coating adds another level of quality by suppressing flare and ghosting even in challenging lighting conditions. A constant F4 maximum aperture throughout the zoom range is also an advantage for movies and stills. No matter what the shooting situation, this lens consistently delivers outstanding performance that has made the G Lens series a first choice for discerning photographers everywhere.

Maximum E-mount mobility advantageCompact, lightweight mobility is part of the E-mount system's appeal, and this lens has been designed to complement and maximize that advantage. Its state-of-the-art optical design simultaneously achieves outstanding optical performance while reducing both the overall length of the lens and the diameter of the front element. You gain mobility and manageability with no compromise in image quality or operation.

Professional focus mechanismAn inner focus mechanism not only contributes to fast autofocus operation, but also keeps lens barrel length constant during focusing for stable handling. Focus drive is handled by an advanced direct drive SSM (DDSSM) system that delivers ample power for smooth focus lens group control. Autofocus is quiet, fast, and precise when shooting stills or movies.

Dynamic perspectives in an ultra wide-angle zoomWith a zoom range extending from 12mm to 24mm, the ultra wide-angle FE 12-24mm F4 G zoom offers the widest perspectives in the full-frame E-mount lens lineup. Optical aberrations that commonly detract from the performance of wide-angle designs have been effectively controlled, achieving excellent resolution throughout the image area. Despite its impressive performance, this lens is remarkably lightweight, compact, and mobile, offering quality and capabilities that will satisfy professionals' and enthusiasts' needs for wider fields of view when photographing landscapes, architecture, and more.

Aspherical lens elementsFour aspherical elements in a new optical design effectively suppress aberrations that commonly occur in wide-angle lenses, achieving impressively high resolution that fully satisfies expectations for the G Lens brand. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped "aspherical" elements restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and ultra-wide angles, and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight.

Constant F4 max apertureConstant F4 max aperture maintains exposure and depth of field regardless of the focal range to which you zoom. When changing your aperture to defocus the background, the areas out of the focal plane appear blurred. This 'bokeh' effect of the blurred background is enhanced with circular aperture blades used in this lens.

7-blade circular aperture contributes to gorgeous bokehWhen changing your aperture to defocus the background, light sources appear blurred. This 'bokeh' effect of the blurred background is enhanced with the 7-blade circular aperture used in this lens. Conventional aperture blades have flat sides creating unappealing, polygonal-shaped defocused points of light. A (alpha) lenses overcome this problem through a design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.

Nano AR CoatingSony's original Nano AR Coating technology minimizes flare and ghosting by suppressing internal reflections and maintaining clarity, even in difficult outdoor lighting conditions, for dynamic range that achieves lifelike detail and gradation with advanced camera sensors. This precisely defined regular nano-structure allows accurate light transmission, contributing to high-quality images, more so than with lenses that use coatings with an irregular nano-structure. The reflection suppression characteristic of the Nano AR Coating is superior to conventional anti-reflective coatings, providing a notable improvement in clarity, contrast, and overall image quality.

Dust and moisture resistant1 for robust reliabilitySony's standard lens sealing is augmented by a lens mount seal that maximizes resistance to dust and moisture for reliable operation in challenging environmental conditions1. Additional details, like rubberized rings that are easy to operate in low temperatures, a customizable focus hold button and a hood lock button, all add up to professional control and convenience.

Instant auto/manual focus selectionInstantly switch between auto and manual focus via an AF/MF switch on the side of the lens. This makes operation faster and easier as you let the camera and lens focus for you, or decide to take control and manually focus on the precise point you chose.

Focus hold buttonThe focus hold button not only performs its primary function to lock focus when recomposing, but can be customized to a number of other functions depending on your needs. In addition to Focus Hold, custom functions include: Grid Lines, Eye AF, AF On, Aperture Preview, Shot Result Preview or Bright Monitoring.

Internal Focus maintains lens dimensionsOnly the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change while focusing. This is especially useful when using the lens for video with a matte box.

Fluorine front-element coatingThe front lens element features a fluorine coating that helps to prevent dirt and fingerprints from sticking, and makes it easier to wipe dirt and fingerprints away if they become attached to the lens surface. This is a lens that can be used with confidence in a variety of challenging outdoor conditions.

Compact, lightweight designA new optical design takes full advantage of the short E-mount flange back distance to reduce both barrel length (4.625") and front element diameter (3.5" max.) while weighing in at only 20 oz. This compact, lightweight design maximizes E-mount mobility.
